Table 7

Mechanical parameters of cement-based material under stress–strain loading.

Test no.	Elasticity modulus (MPa)	Poisson ratio	Stress value (MPa)	Strain value (%)	Area integral
Control sample	10619.5 ± 0.3	0.132 ± 0.06	24 ± 0.1	0.9 ± 0.02	14 ± 0.02
ZRJ-S1-(0.05 wt%) reinforced sample	6940.2 ± 0.1	0.23 ± 0.04	28.5 ± 0.1	1.07 ± 0.01	28 ± 0.01

Note. Test pressure of 20.7 MPa and test temperature of 119°C, with loading rate at 1.6 kN/min.
